Can't access email on Wi-Fi overseas

Can't access email on Wi-Fi overseas

This is the 2nd time in the past 3 months that I am without email overseas. None of the TWC or Spectrum log in sites will allow me to access. Had been with TWC for many years of overseas travel. This is something new since Spectrum took over. I thought they fixed it for me when I was home and between continents. But it is not fixed at all. Spectrum must be aware that their product is not working worldwide as other providers offer. Looks like I'll have to change providers upon my return to the USA. Huge problem not being addressed by Spectrum.
